This working paper presents guidelines for implementation of a school reorganization model designed to facilitate the individualization of instruction. The POISE model (Pupil Oriented and Individualized System of Education) is presented as it was developed for use by the Southwestern New York Association for the Improvement of Instruction and the Teacher Education Research Center of the State University at Fredonia in cooperation with participating schools which agreed to identify and undertake changes in school organization including reassignment of staff, pupils, resources, and facilities in accordance with the patterns of reorganization identified for facilitation of work with individual pupils. Each component of the model is described in detail. Basic components include 1) curriculum decision-making responsibilities at team, school, and system level for the professional staff; 2) development of a school information system to provide appropriate data for individualizing instruction; 3) development of an individualized reporting system; 4) a system of instruction which seeks optimum individualization; 5) the development of differentiated staff roles; 6) the assignment of learners to an ungraded instructional pool; 7) reallocation of space and facilities; and 8) a high degree of school-community involvement. Included are a 20-item bibliography and a 13-item list of illustrative sources of information about individualized instruction. (JS)
